Sit on the Left side of the plane for the best views on flights from Seattle to Orlando. The left side wins overall due to the spectacular Mount Rainier and Cascade departure views, which are among the most dramatic takeoff scenery in the continental US. The right side has a slight edge on landing, but the Cascades at departure outweigh the flat Florida approach scenery. Passengers who want both should sit left and simply cross the aisle during descent.

During takeoff from Seattle Tacoma International (SEA), sit on the Left side for the best views. SEA typically departs south on runways 16L/16R, then turns southeast.

Notable sights include: Mount Rainier (14,411 ft, unmistakable snow cone to the southeast), Elliott Bay and downtown Seattle skyline, Lake Washington stretching north-south, Mount Adams visible further south on clear days.

When landing at Orlando International (MCO), sit on the Right side for the best views. MCO typically lands on runways 17L/17R or 18L/18R, approaching from the north. The right side faces west over the Orlando metro area, Walt Disney World's distinctive resort complex, and the chain of lakes that define central Florida's landscape. The left side sees mostly flat pine scrub and the St. Johns River floodplain. Notable sights include: Walt Disney World resort complex (visible as a dense cluster of themed structures and the Seven Seas Lagoon), chain of interconnected lakes across Orange and Osceola counties, Orlando downtown skyline to the northwest, International Drive hotel corridor.

The flight from Seattle Tacoma International (SEA) to Orlando International (MCO) takes Approximately 4 hours 45 minutes to 5 hours 15 minutes.

The route crosses the Oregon Cascades including Mount Hood, then tracks southeast over the Great Basin's high desert plateau in Nevada and Utah. The Colorado Plateau and its canyon systems pass below around the midpoint. The route then crosses New Mexico and Texas before entering the Gulf Coast lowlands of Louisiana and Mississippi, followed by the flat pine forests and wetlands of Alabama, Georgia, and northern Florida.
